CLOCK OPERATED ELECTRIC SWITCH AND ALARM BUZZER CONTROL DEVICE Filed001;. 15, 1959 7 Sheets-Sheet 7 ctocnornna rnn ELECTRIC swrren ALARMnuzzsn CONTROL DEVICE Ronald M. Bassett, Chicago, Ill., assignor toInternational- Register Company Chicago, III, a corporation of IllinoisFiled Oct..15, 1959, Set. No. 846,632 12 Claims. (Cl. 58- -38) Thepresent inventionyrelates to an improvedclockv operated electric switchand alarm buzzer control device,

adapted primarily tor use with radios, but, as will hereinafter appear,the device may also be used with television sets and other appliances.

In the preferred adaptation, the device is built directly into the radioor'tele-vision set, but the device can'also be built into the form. of aseparate clock operated conmy improved control device is capable ofperforming,

selectively, any desired one'of the following control functions oroperations: 7

(f1 Turning the radio on automatically at a preselected time, and thenafter the lapse of a short time interval, such as or minutes, causingthe alarm buzzer to automatically so nd.

(2) Turning the radio on automatically'at the preselected time, withoutautomatically sounding the alarm buzzer.

(3) Turning the radio off automatically after a predetermined lapse oftime, such as 151 to 30 minutes after going to bed; and thenautomatically turning the radio on again at a' preselected time, such asthe next morning.

(4) Turning the radio off automatically after a predetermined lapse oftime, such as to 'minutes after turning'the radio on going to bed;without automatically again the next morning;

(5) Causing the alarm buzzer to sound automatically at a preselectedtime, without'causing sound from the radio. I I

(6) Shutting oil? the alarm buzzer manually in such manner that it willautomatically sound again after a short lapse of time, such as 5 or 6minutes. This buzzer delayrepeat mechanism may be manually trippedseveral times after each sound of the buzzer so as to obtain severalsuccessive 5 minute periods for snoozing or going back to sleep; or,alternatively, two or more of the delay intervals may be totalized, ifdesired, by manually actuating the control lever several times at once,thereby obtaining a longer delay interval before the alarm buzzer soundsagain. To avoid the complexity of a technically descriptive title forthis latter mechanism, I have called it the 40-Winker mechanism.

, (7) Turning the radio on manually.

(8) Turning the radio off manually.

One of the particular objects of the invention is to provide an improvedcontrol'device of the above general description wherein the indexingposition of. the index knob always indicates the true positionofthe'electric switch that controls the radio. That is tosay, themultiple position indexing knob always-goes automatically to its ONindicating position whenever'the radio goes on. Thus, a glance at thisknob shows whether the radio is turned on or oif, regardless of thevolume setting of the UnitedStates Pat we station has gone off the air.In theflabsence of this tenor indefinitely.

'in its OFF position, hereinafter ture it is very easy to leave theradioenergized all night Another object of the invention is to provide asimplified and improvedcontrol device capable of obtaining all oftheabove control functions.

Another object of the invention is to provide such a control devicewhich is extremely compact in its dimensions so as to occupy the leastamount of space, which is a very desirable feature when the device is tobe built into arelatively small table model radio, a small tele visionset or other small appliance.

Another object of the invention is to provide such a control devicewhich is simple and inexpensive to construct so that it can favorablycompete in the highly competitive field of radio clock switches, timers,etc.

Other objects, features andadvantages of the invention will appear fromthe following detail description of a preferred embodiment thereof. Inthe accompanying drawings illustrating such embodiment:

Referringfirstto FIGURE 1, the clock switch 30 comprisesaclock dial 31.having hour markings 32, relatively towhich the. hour andminute. hands 34;and 35 indicate theltimeof day. Rotating concentrically of the hourand minutelhands is a. sweep second-hand 36 which gives an approximatesecond indication and which also gives a visualindication as towhetherthe synchronous electricrnotcr of the clock is-running. Also mounted forrotation concentrically of the hour, minute and second hands, isthemanually settable time switch indicating hand 37 which is adaptedtobemanuallyset at the time at which it is desired that the radio(orother appliance) be turned on In the typical installation atable orconsole type radio, the clock dial3 1 andthe four hands 64-371 areprotected by a cover glass with a, surroundingjbezel, which-are netshown because they will varywith each radio manufacturers requirements.Projecting from the right and left handi edges of the clock dial,eitherlthrough orou'tside such cover glass, are rotatable settingshafts41- and;42 onwhichrotatabie settingknobs 43 and, 44 are. mounted:, 'Ihesekmbs carry indicating ribs 435 and 44 which, in conjunctionwithindicia4 7. and 48 on the face. oft he dial, indicate the rotativepositions into which the 7 turn offautomatically.

. 4 setting knobs 43' and 44 can be set. The right hand knob 43 is anindexing knob which is movable into any one of four different indexingpositions which are printed on the .face of the dial, and occur in thefollowing sequence for a right hand or clockwise rotation of the knob43; (1) OFF, (2) RADIO-ON, (3) RADIO-A and (4) ALARM." When there is nointention of having the clock switch turn on the radio or sound thebuzzer at a preselected time, or having the clock switch maintaincurrent to the radio, this right hand knob 43. is maintained in thebottom or OFF position, such being the normal position.

Referring now to the left hand setting knobv 44, this normally standsinthe position shown with the rib 44. point upwardly, the knob beingrotatable therefrom through approximately 180 in a right hand orclockwisedirection. This knob 44. eflects a so-called SLEEP 'SWITCHoontrol which the user sets at night upon going to bed, forautomatically turning the radio off after apredeterrnrined lapse oftime, such as 20, 40, 60 utes, etc. The knob 44 can be rotated toposition the rib. '44 at any point of the arcuate scale, between theupper end designated 0 down to the lower end designated, 6 0. The 0 endof the scale denotes that the SLEEP SWITCH control 4 5 is off,;and the60 end of the scale denotes that the SLEEP SWITCH control. is set tokeep.

the radio turned on for a 60 minute interval, when it will The manualsetting of the hour and minute clock hands 34 and 35, and the manualsetting of the automatic timer indicating hand 37, are both performedthrough a rear setting knob mounted on a rotatable and shit-table set-.ting shaft 511- projecting rearwardly from the back side of the clockswitch assembly (FIGURE 3) One of these setting operations is performedwith the knob and shaft shifted inwardly, and the other settingoperation is pen.

formed with them shifted outwardly, as will be later de scribed in,detail.

Another manually operable control projects from the right hand side ofthe clock switch assembly, this being in the form of a verticallyswinging pivoted lever 52 which is adapted; to be stroked downwardly oneor more successive times'by ones linger'when, after the automaticturning on of the alarm buzzer (either following or independently of theturning on of the radio), at the preset,

time, the sleeper wishes to get more sleep, such asanother 5, 10, or 15minutes. He can obtain any of these addi-u tional time delays inbuzzeroperation by stroking the lever 5-2 downwardly either once, twice,or three times. I have commercially named this apparatus as the 40-.Winker mechanism 55 of my improved clock switch. Having brie-flydescribed-the function of the manual controls, I- shall, now describethe detailed construction 0 the clock switch.

The assembly comprises a front mounting plate 61 and a rear base plate62 which are secured together in spaced relation by a plurality ofspacing legs 63a, 63b and 63c (FIG. 7). These spacing legs are bentforwardly from the rear base plate 62' and pass through slotted holes 64in the front mounting plate 61,' following which spurs 65 at the ends ofthe mounting legs are twisted sidewise across the front edges of theslotted openings 64 (see FIG- URE 17). A face plate 66 is securedto thefrontside "in the forwardly offset top and bottom flanges ,67. of thefrontmounting plate. t

' Mounted' on the back Secured to the frontend of this arbor 1 77 is theclock second hand 36. Secured to the large' gear J wheel-76 is .a pinion78 which meshes with alarge gear wheel 79 journaled on a pivot shaft 81having its ends 4 mounted in the fnont and rear mounting plates.Extending forwardly from the large gear wheel 79 is a relatively longpinion 82 which meshes with a large gear wheel'83 disposedconcentrically of the second hand arbor 7 7.

Disposed on the front-side of the large gear wheel $3 is a smallergearwheel 84 which is secured to a minute hand arbor or sleeve $5. Thisminute hand sleeve 85 surrounds the secondhand arbor 77 and carries thecloclcm-inute hand 35 on its front end. The motor driven drive from thesynchronous motor unit '72 is transmitted from the large gear wheel 83to the aligned smaller gear wheel 84 through a friction slippage clutch86 to permit manual setting of the hour and minute hands 34- and 35relatively to the clock dial. general type of friction slippage clutchis old and well known and need not be described in detail. a I

Meshing with the smaller gear wheel '84 is a large speed reducing gearwheel 88 which has free rotative mounting on the pivot shaft 81. Securedto this large gear wheel 88 isa pinion 91 which meshes with a large gearWheel 92 that is mounted on the clock dial axis. This large gear wheel92is secured to the rear end of an arbor sleeve93 which surrounds theminute hand arbor sleeve 85, such arbor sleeve being both rotatable andaxially shiftable upon the minute hand arbor sleeve 85, the hour hand 34being secured to the outer end of this. axially shiftable arbor sleeve93. The pinion 91, with which the shiftable gear wheel 92 meshes, isrelatively long so that the shiftable gear 92 will remain in'mesh withthis long pinion 91 tends to hold the shiftable gear whe'el92 and amber93 V thrust forwardly.

Mounted forwardly of'the shiftable gear wheel 92, and

' radius, whereby these two sets of humps move into contact with eachother once every'twelve hours for axially displacing the shiftable hourhand gear in a rearward direction. Each hump has a gradually slopingleading end and trailing end, so that manually operated time set-j tingscan be set up by either direction of rotationof the manually settablegear 95. -This particular relation of hour hand gear and time settablegear having coaoting 'pairsof axially displacing humps is old and wellknown, being disclosed for example, in, prior Patent, 2,816,969 issuedto William P. Gallagher and Ronald M. Bassett on December 17, 1957.

It is opportune attthis point to describe the manner in which the rearsetting knob 50 is operative toset up different selected time settingson the manually settable gear. 95, and is also operative to manually setthe hour and minute clock hands 34 and 35. Referring to FIGURE 5, itwill be seen that the setting shaft 51, on which this knob '50 ismounted extends through the rear base plate bearing against the backside of the front mounting plate 61 is a manually settable gear 95 whichis secured tothe rearend of a short outer arbor 96 that surrounds theshiftable arbor 93. This outer arbor 96 extends through the fnontmounting plate 61 and mounts the time settable pointer 37 whichindicates the preselected time when the clockswitch is to operateautomatically. The time set table gear 95 is spaced forwardly from theaxially shiftable hour hand gear 92, and projecting toward each otherfrom the opposing faces of these two gears 92 and-95 are ooacting humps97, 97 and 98, 98'wvhich, at the preselected time, engage each other andshift the hour hand gear 92 rearwardly for trippingithe electric switch,and for sounding the buzzer in certain settings, as will be presentlydescribed; The humps 9'7 and 98 project 'forwardly from diametricallyopposite points of the hour hand gear 92, with the hump 97 traveling ina circle of relativelylarge radius, whereas the other hump 9% travels ina circle of relatively small radius: The other two humps 97 and 98project rearwardly at diametrically (opposite points from the timesettable gear 95, with the hump97 traveling'in a circle of relativelylarge radius, and the hump 98f traveling in a circleof relatively small62 and front mounting plate 61, being rotatable and axially shiftabletherein. Fixedly secured to this setting shaft directly in rear of thefront mounting plate 61 is a double pinion hub 104 having a front set ofpinion teeth 1% and a rear set of pinion teeth 106. When this doublepinion hub 104 is in the forwardly shifted position shown in FIGURE 5,the frontset of pinion teeth 165 mesh with the peripheral gear teeth onthe time settable gear 95, whereby rotation of the knob 50 is thenoperative to rotate the settable gear 95 into any preselected timeposition, as indicated by the front indicating hand 37. When the pinionhubv 164 is shifted rearwardly into the dotted line position shown inFIGURES, the front set of pinion teeth 105 are moved out of mesh withthe gear teeth 95, and the rear set of'pinion teeth 166 are moved intomesh with the peripheral teeth 88' of the speed reducing gear wheel 88interposed in the time train connecting the clock hands 34!- and 35.Thus, rotation of the setting knob St) in this rearwardly shiftedposition is operative to manually adjust the time setting of the hourand minute clock hands 3'4 and 35. Punched inwardly from the rearv baseplate 62 is a forwardly projecting stop lug or tongue 107 which limitsthe rearward shifting movement of the pinion hub 104 to the dotted lineposition shown. The time settable gear 95 is frictionally held in any ofthe positions to which it may be manually adjusted through rotation ofthe setting knob 50, by the friction exerted by wayof a cupped springwasher 108 (FIGURE 5) confined between the front side of front mountingplate 61 and a front flange 96' projecting from the outer arbor 96carrying the time indicating'pointer 37. The friction exerted bythecupped or spring washer ltl8-prevents-the time settable gear 95 beingdragged along by the" time driven gear 92 through the engagement of thehumps 9'793'.

- .It will be seen from the foregoing that the time settable gear 95 canbe rotated to any desired time selecting position through rotation ofthe rear setting knob 50, and that this will locate the diametricallyopposite cam humps 97' and 98' in a certain fixed angular positiondenoted on the clock dial by the position of the time selecting pointer37. When thecontinuously rotating time driven gear 92 brings its innerand outer diametrically opposite humps 98 and 97 into engagement withthe stationarily positioned cam humps 93 and 97 the uphill slidingcontact between the coacting humps'causes the time driven gear 92 toshift axiallyinwardly or rearwardly, such shifting movement tripping atime responsive tripping lever 110 which performs successive trippingfunctions having to do with the switch closing and buzzer soundingoperations. Before describing in detail this time responsive trippinglever 110 audits associated sequence lever, buzzer control arm, etc.,

, scribed.

first-briefly describing the electric switch and the sounding aninsulating housing 116. which has anchored mounting in the frontmounting plate 61 and rear base plate 62; A rectangular lug 117 ({FIGURE17) projects integrally from the front end of the switch housing 1 16andhas anchored fittingwithin a rectangular opening 118 which is punchedoutin the front mounting plate- 61; and the outer portion of the switchhousing has anchored mounting in'a rectangular aperture 119 which ispunched out in the rear base plate 62. Apairof relatively longcontactsprings 121 and 122 (FIGURES 3 and 4) have their outer or rearends anchored inthe rear end of the switch housing 116 for establishingelectrical connection with the circuit of the radio or'iother appliancebeing controlledby the clock switch; Carried at the forward ends ofthese contact springs 121,122 are the cooperating electrical contacts123 and 124. which are normally biased to remain out of engagementwitheach other. The switch housing 116 is formed with a transverse slot126 adjacent tothe rear base plate 6 2, and mounted in this slot isaninsulating slide 127 which is operative to press the two contacts 123and 124 together. The actuating end of this slide 127 projects from theinner side of the switch housing in position tobe depressed into switchclosing position'by a switch actuating lever 130" (FIGURES 7, 8, etc.)which is of bell crank formation and is'pivotally mounted intermediatethefront and rear plates 61 and 62 :on a transverse mounting pin 135which has its ends mounted in these front and rear plates. One arm 13 1of this bell crank lever 130 is formed with a rearwardly bent lip orflange 132 which is operative to transmit inward switch closing motionto the slide 127, this switch actuating flange 132 having a downwardlyinclined lip 1 32' at its outer end. The other arm 133 of the bell cranklever 130 has an angular extremity-134 which is adapted to be actuatedby a carn13'6 mounted on the shaft 42 of the"SLEEP SWITCH knob 44, aswill be later de- When the clock switch 30 is built directly into theradio housing or cabinet, the projecting ends of the switch contactspringslZrl, 122 are wired directly to the radio circuit within thishousing; but where the clock switch 30 isenclosed within an independenthousing in theform of a control appliance separate and apart from theradio housingthese switch contact springs 121 and 122 are electricallyconnected with a plug in receptaclesocket mounted in the independenthousing and adapted to receive the prong type of receptacle plug at theend of the extension cord" connecting with the radio or other applianceto-be' controlled.

Referring now to the sounding buzzer, this comprises a vibratory reed140*- (FIGUR'ES 4, 7, etc.) which in its sounding condition is adaptedto vibrate substantially in resonance with the alternating currentmagnetic field prevailing within-the synchronous drive motor 71. Themain body portion. of this reed is almost as wide as the space I betweenthe front and rear frame plates 61, 62, and the anchored end of thismain body portion has a slightly royckable mounting between said frameplates on cars 142 which project outwardly from the edges of the reedand engage in slots 144. formed in bothmounting plates. These slotshave-narrow lower ends 144a (FIGURES 7, 8, etc.) in whichthc lower edgesof thev =ears.14-2 seat, and the slots have wider upper ends 144b thatpermit the slight rocking movement of the anchored end of the reed asthe free end of thereed is flexed'inwardly and outwardly with respect tothe magnetic fieldofthe synchronous motor 71. Projecting'rearwardly thefree end of the vibratory reedis a relatively long arm 146 which hasalaterally bent end 147- enteringa. slot 148 in the side of the motorhoussing: (FlGU-RE4), thislaterally bent end. 14-7 being adcontrol arm160 is formed with a relatively longiiat dwell mg 151 (FIGURE 17 whichprojectsforwardlythrougli the 4(I-Winker mechanism which will be laterdescribed.

A thin oblong leaf spring 153, preferably composed of berylium copper orthe like, and having a bowed curvature, is interposed between the'outerside of the main body of the vibratory reed and the adjacent edge of thespacingleg 63a extending forwardly from the rear base plate =62. Thelower portion of this leaf spring has. tongues 154 which extendoutwardly through the wide portions 14% of the slots 1'44, and a fingerportion 155? at the-upper end of this leaf spring bears inwardly againstthe vibratory reed so as to normally bias this reed in aninwarddirection for causing the laterally bent end of the reed to bepresent .ed into theiniluence of the alternating current magnetic lip isadapted to be deflected an upward and outward direction by a pivotallyswinging buzzer control arm 160.

when the buzzer is to remain silent; and when the buzzer is to soundthis buzzer controljarm swings into a-position which removes the outward"deflectingforce from the lip 158 so that the-vibratory reed 1'40 isfree to vibrate. More specifically, the swinging outer edge of thebuzzer 166a which is operative, when in engagement with the; lip 15%, todeflect the reed outwardly into a non-sounding position. Beyond thisdwell leti'a is a valley 160b-and beyond the valley is a cam slope 160c. When the valley 160 b registers with the lip 158 the reed is freeto vibrate, and when the cam slope 160a: moves overagainstthe lip 158the reed is, again deflected outwardly into its non: sounding position,as will be described more in detail later.

Reverting back again swingrearwardly whenever the engagement of thebumps 97, 97 and 98, 98' at a preselected time causes the slidable hourhand gear 92 to shift axially rearwardly. This oc- V curs in allindexing positions of the indexing or'sequence knob 4-3, except when theknob is in the (#1)OFF position, (FIGURES 7 and 7A), as will bepresently described. As shown in FIGURES 7, 8, etc. this lever 110 hasan oval or polygonal-shaped opening 163'there-in through which passesthe compression spring 94, minute mounting for this end of the leverinthe front mounting plate 61. A semicircular tongue 166 projectsforwardly from the center of the front edge of the flange and in thepivotal mounting of thelever thistonguein a-downwardly bent form isthreaded forwardly through a rectangular slot 167 (FIGURE 17) intheiron-t mounting plate 61; or is passed forwardly through this slot'ina straight form and is then bent over in adownwardly ex.- 7 tendingdirection on the front side of the mounting plate,

whereby the lower end of the lever is provided with a hingedmountingpermitting fore and aft-swinging move:- rnent of the lever with theaxial sh-ifting'of the hour hand gear 92.

Pivotally supported at the opposite swinging end of this time responsivelever 110 is a spring biased flipper latch 170 which is adapted toengage latching-shoulders on the buzzer control arm 1-60 andon asequencecontrol lever both ofwhich control memberslie below the to'thetime responsive trip-ping lever 110', it will be recalled that thislever is, caused to swinging end ofthe time resp onsive lever 11%. Thepivotal i mounting of the flipper latch 170 is effectedin a hook-"shaped mounting notch 171 formed in, the'xlever, see FIGURE 8), thisnotch having a closed outer end 172 and ,closed side edges 173 buthaving an open inner e'ndt- As shown in FIGURES and 16, the flipperlatch 17% comprises a latching shank portion 174 which is arranged toproject forwardly or downwardly from the under side of in the oppositeside edges of this shank portion 174 are the lever 110 substantiallyatright angles thereto. Formed notches 175 whichare adapted-to engagewitharather punched out of the front frame plate 61. This upper armportion176 is preferably bent with a slight inclination in the direction of thepull of the tension spring 17-7, and I bent forwardly from theside-edges of this upper arm portion 176 are stopwings 170' which areadapted to have stop abutment against the "closed end 172 of themounting notch 171; These stop wings limit the spring urged rockingmovement of the flipper latch 17b (in a clockwise direction as viewed inFIGURE. 15 to an'upright position with thelatching shank portion 174projecting inwardly at'right angles to the 'lever 110. However, theflipper latch 170 is free to swing reversely (in a counterclockwisedirection asviewed in FIGURE '15) in opposition to the tension of thespring 17 7 whenever the latching shoulders on the control membersbeneath the lever 11tlmove toward the right (FIGURE 14) against the backside of the latching shank portion 174.

Punched downwardly from the swinging end of the time responsive lever110, along its other edge opposite to the flipper mounting notch 171, isa lug 179 which is adapted to abut against the "back surface of themounting plate 61 for limiting the inward swinging movement ofthe lever110 substantially to the parallel, position shown in FIGURE 8A; it beingnoted in this regard that the downward inclination of the tension-spring177 tend-s'to-sw ing the time responsive lever 111 inthis direction, inaddition to'normally holding the flipper latch 170 in latching position.

The operatingrelati-cnship is such that when thisindem'ng knob 43 is rotated intoeither one of the tour indexingpositions designated OFFf fON,

AUTO; and ALARM, the switch sequence actuating member 180 iscorrespondingly rotated to occupy the successive positions showninFIGURES 7, 8, 9 and 10. Limited rotative movement is transmitted fromthe rotatable sequence member 180 to the buzzer controlling arm16llthroughan arcuate slot 191 formed in the sequence member l tlandhence rotating therewith, into which rotatable slot extends a lug 192bent forwardly (from the hub portion 193 of the buzzer controlling arm160. This rotatable arcuate slot191 has a top stop shoulder 191' and abottom stop shoulder 191" adapted to have cooperating stop engagementwith the top and bottom edges respectively of the swingable lug 192. Thelug 192 extends forwardly through the, swinging motion trans-.

m-itting slot-191 and enters a stationary ancuate slot 194 punched outof the front mounting plate 61 (FIGURE 17). This stationary arcuate slot194 has, the same con-,

centric radius as the rotatable arcuate slot 1'91, but is of shorterangular length than .said rotatable slot.191; As best shown in FIGURE17,-thisfstationary slot194likewise has top and bottom stop shoulders194' and 194 adapted to have stop engagement with the top and bottomstud 134 which may have mounting support at one end in the frontmounting plate 61; or they may be mounted in preassentbled relation on asimilar pivot stud which has rotatable bearing mounting in the front andrear mounting plates 61 and 62, these two control arms 160' and 180havinglimited relative rotation therehetween. The sequence controllingmember 180 comprises a large circular hub portion 182, from whichextends an outwardly projecting arm 183 which is adapted to operate theelectric switch by rotatively wiping'across the top of the lip 132 oflever thereby depressing the contact actuating slide 127into switchclosing position. This switch actuating sequence member is continuouslybiased to rotate ina counterclockwise direction (FIGURES 8, 9; etc.) by

,a torsion spring185 which is coiledaround the projecting edgesrespectively of the swingable lug 192, whereby this stationary slot 194cooperates with the rotatable slot 191 and lug 192 to establish the twoend stops which determine the end limits of the rotary motion of themanually actuated switch control or sequence member 180. The outwardlyextending portion of the buzzer controlling member 160, which is formedwith the dwells and valley 16tla-160c at its extremity, has an outwardlyand upwardly bent offset 160 from the plane ofthe hubv portion 193st)that this offset arm portion will clear certain latching shoulders whichare carried by the sequence or indexing member 180, these latchingshoulders passingwbeneath this upwardly offset buzzer controlling arm.Such upwardly ofiset buzzer controlling arm lies in a plane, however,that will permit such controlling arm to pass beneath the outerextremity of-the time responsive lever 110 in any of the inward andoutward positions of this lever 110. g A

The buzzer controlling member 160- and the switch controlling member 180are provided with latching shoulders which rotate under the lowerlatching edge of flipper latch 176 along three different radiidesignated r1, r2

. and r3. The buzzer controlling arm 160 has a singlelatch- This singlelatching shoulder {195 is of relatively short angular length, and isbent upwardly from an extension 1% projecting from the hub portion 193ofybuzzer controlling member 160. The switch controlling member 180 isprovided with three latching shoulders 196, 197 and 198 all bentupwardly from the outer portions of the hub 182;. The first of thesethree latching shoulders, in the counterclockwise sequence around thehub 182 (FIGURES 8, 9, 13,"etc.) is" designated 196 and rotates at theintermediate radius r2. This first latching shoulder 1% carried by thehub 132 projects upwardly to a height 1 above any of the other latchingshoulders 195, 197 or w 198 (see FIG. 14), and has a relatively longfiat top,

longer than'any of the other shoulders. The other two latching shoulders197 and 198 carried by-the hub 182,

both rotate-one behind 'the other at the outer radius r3;

These'two latter shoulders have top edges of the same; height, and thisheight is the lowest in the series, being t V flipper latch. 1 70 (ire.the left 'hand face of shank portion 174,FIG.. 15 as these shouldersbecome successively unlatched' therefrom.

However,the flipper mounting, of the latch 170, the tension'of the spring 177'andthe torsion of the spring 185 are such that a firm rotative fingerpressureapplied to. the indexing k nob 43in either direction of rotationis operative to cause manual rotation of the twoicontrolmemrbersI60-and180- in either direction, in

opposition t-o'the-tension spring 177' or torsion spring 185, wheneverit is desired to manually turn the indexing knob 43 i-n either directionto a different indexing position.

I shall: first describe the ;OFF, ON, AUTO and ALARM positionsillustrated in FIGURES 7, 8, 9 and 1-0,. describing the sequence ofoperationsoccurring when the sequencecontrol member 180 revolves in aclockwise direction. ('FIGURESR; 9 and 10) in passing through thesediiferent'sequence or indexing positions.

\ FIGURESJ andI 7A illustrate theparts in the OFF or: #lposition,in-wh'ich the-switch control member 180 and the-buzzer control member160 are disposed at the .limit of: 'their rotative movement in onedirection, the parts being manually turned into this OFF or #1positionthrough manual rotation of -the indexingknob 43.

Tirestop. limit otthe rotative movement in this direction is established by the bottomedgeof the motion transmitting lug 192?engaging against the bottom stopshoulder 1 94 ofstationary slot 194, and-the top stop should-er 19'1 ofrotata'ble sloti191' abutting the top edge of thelug 1922. Referring toFIGURE 7A, it will be seen that in this OFF positiontheflipper-latch 70is restingon top of the relatively-high flat stop shoulder 196, in whichposi tionthetime-responsive lever 110 is tilted up to an anglewhich-takes it beyond'the operating influence of the axially shiftabletime driven gear 92, in'consequence of which theitime" selectingmechanism. can operate indefinitely without transmitting any movement tothe time responsive lever 110; Inthis OFF position of the parts, theswitch actuating arm-183 extends downwardly at such inwardly inclinedangle that the switchiopierating slide 127 remains in :its uppermostposit-ionto hold the electric switch open. A'lsogin this OFF positionthe, upper endI191f of the rotatable:arcuate-slot191hasreacteddownwardly' against the motion transmitting lug 192: tooscillate the buzzer oontrol*arm;160 in such: direction of rotation(clockwise, as viewedin-EIGURE; 7).. as to; bring therelatively longdwell 160a under the lip 8{f or holding" the buzzer reed flexedoutwardly into its non-sounding position.

FIGURES 8 and 8A showthe position of the parts when the indexing knob 43is manually rotated out of the OFF (#1) position into'the ON (#2)position.- The switch controlling member 180 swings the arm 183 into asubstantially vertical position, thereby rocking the switch actuatinglever 130 and depressing the switch slide 127 down into switchclosingposition. This motion of switch actuating member. 180 is nottransmitted to the buzzer control arm 160 because the arcuate slot191'merely' it occupied in FIGURE 7, in which position the vibratory lreed is flexed outwardly into its non-sounding position. The switchcontrolling member 180' is latched in this ON (#2) position, with theradioturned on but the buzzer not sounding, by the action or" theflipper pawl 170 snapping off the flat top of the high latching shoulder196 down into engagement against the forward or leading edge of thisshoulder, as illustrated in FIGURE 8A. i

FIGURES 9 and 9A show the operating positions occupied by the parts whenthe indexing knob 43 is manually rotated through the next step up totheAUTO (#3) position. This rotates the switch control member I 180 toswing the downwardly extending arm 183 ch of the high part of the switchactuating lever 130, thereby permitting the switch to. move to opencircuit position and turn the radio off. The buzzer reed still remainsflexed outwardly into its non-sounding position. because the frictionalpressure of its curved end 158 against the fiat dwell 160a establishesenough friction against the end of the buzzer control arm 160. Thelength of the slot 191 permits this further angular movement of theswitch actuating arm 180' without transmitting corresponding angularmovement to the buzzer control arm 160; itbeing-noted, however, that thebottom edge of the motion transmitting lug 192 is now being engaged bythe bottom end 191" of the rotatable slot 191. The parts are yieldinglylatched in this AUTO position'by the action of'the latching shoulder 197in rotating in a clockwise direction under the flipper latch 170 so thatthe flipper latch'drops down into latching engagement against the rightangle leading edge of the latchingshoulder 197.

FIGURES 1 0 and 10A show the operating position" of the parts when theindexing knob 43' has'been manually rotated through the final step inthis direction, into the ALARM (#4) position. Inthis position, theswitch actuating arm 183 has been rotated still furtheraway from theswitch actuating bell crank lever and the lower end 191 of the slot 191has imparted rotating movement to'the lug 192 for swinging the buzzercontrol 'arm in a clockwise direction, into the position illustrated inFIGURE 10. In this fourth position of the parts, the abutment of thebottom stop shoulder 191" of therotatable slot 191 against thebottom'edge of lug 192, and the abutment of the top edge of lug 192against the top stop shoulder 194' of stationary slot 194'estab lishesthe stop limit of rotation in this direction of control member 180' andsetting knob 43-. valley 16% has been swung beyond the hp 158 of thebuzzer'reed, so that the cam slope160c has-been brought up against thelip 158 for continuing to hold the vibratory reed flexed outwardly intoits non-sounding position; Thus, in this ALARM position, the radioremains turned olf and the buzzer remains in its non-sounding conditionThe parts are yieldingly latched in this relae tion' by theend latchingshoulder 198' of the switch controlling member 180 moving clockwiseunder the flipper latch and having: its rightangle edgelatched behind orbeyond'the flipper latch. Concurrently with the swing; ing. movement ofthe switch controlling member therbu'zzer control arm 1'60hasrevolvedcorrespondingly In this position, the

and this has brought the back side of the flipper latch, with the twolatching shoulders 1% and 19$ both occupying aligned radial positions inengagement against the back side of the flipper latch. The parts willremain in this ALARM (#4) position until the manual rotation of theindexingknob 43'causes the parts to assume a difierent positiom or untilthe arrival of the preselected time set upon the timesettable gear 9 5,whichresults in the timeresponsive lever 110 automatically Swingingoutwardly'through the first stage of its time responsive latch trippingoperation.

- We are'now starting the reverse direction of rotation ofthe switchcontrolmember l-eti and indexing knob 43, which reverseorcounterclockwise direction of rotation or the switch control memb'er18d (FIGURES 11 and 12) results a different sequence of some of thecontrol functions from what occurred during the clock- 'Wise rotation ofthe switchcontrol member 1189. V FIGURES 11 and 11A show the positionsassumed by the parts after the time responsive lever 110 has movedoutwardly through the first stage of its automatic the latching shoulder'19s a the l buzzer control arm back into latching engagement against Ain the reverse direction to the ON (#2) position, which recloses theradio switch 115 but still leaves the lip of the vibratory reed bearingagainst the long dwell 160a (see FIGURE 8).

tripping operation, which first stage of automatic tripping operationinitiates the first stage of such reverse or counter-clockwise rotation.The outward movement of this lever 110 is relatively gradual because ofthe relatively slow outwardcarnming of theftime driven gear 92 caused bythe engagement of the sloping cam humps 97, 97' and 98, 98, and inconsequencefofsuch slow outward camming the flipper latch 170first'releases the latching shoulder 198- carried by-the switchactuating member 180, before the flipper latch '170 releases'thelatching because of its above described setting.

shoulder-195 carried by the buzzer control arm 1663.

This prior releasing of the latching shoulder 1% occurs becausethe topof such shoulder is below the top of the inner shoulder 195. Theflipper. latch 170, in releasing the first outer shoulder 198, alsoreleases the second outer shoulder 197 because these two shoulders areof the same height. As a resultof this action, the switch control member180 and the indexing knob 43 both revolve back through the AUTO (#3)position into the ON (#2) position, which brings the arm 185down intoits vertical switch closing position. The radio is immediate-- 'lyturned on and begins playing, assuming that the volume control has beengiven the proper setting. The buzzer control arm 160 remains in the sameposition shown in- FIGURE 10 for the timerbeing, with the spring bias ofthe vibratory reed reacting against the cam slope 160a,

and the arcuate slot 191 still having idling motion with respect to thelug 19 2. v I

Meanwhile, the time responsive lever 116 continues to move outwardly atits gradual rate unit, after the lapse of a predetermined time interval,such as 10 minutes, the flipper latch 170 has been raised high enough toclear the inner tripping shoulder 195 carried by the buzzer control arm160, This'control arm 160, which has been standing in theposition shownin FIGURE 10 with the reedlip I58 being biased or urged outwardly byreason of bearing against the cam slope 1600, is immediately cammedover: counterclockwise by the spring bias of the reed acting againstthis cam slope 16th:, as a result of the unlatchi ng, of thelatchshoulder 195, sothat the valley depression 16012 thereupon movesinto registry with the lip on the vibratory reed..

FIGURES l2 and 12A show this position of the parts,

with the valley depression 16% in registry with the lip on the reed,which completely frees the reed so that the buzzer'thereupon beginssounding, and willcontinue to sound until the indexing knob 43 ismanually turned down into the OFF (#1) position, which swings the longflat dwell 160a-under the lip end of the vibratory reed (FIG URE 7) sothat thesounding of the buzzer is stopped.

If it is de'siredth'at the playing of the radio be allowed I tocontinue, after the soundingof the buzzer 'has'been stopped, theindexing knob 43 isrnerely turned back "If it is desired to have theradio turn on automatically I without having the buzzer sound shortlythereafter, the

indexing knob 43 is placed in the AUTO (#3) position (FIGURE 9) insteadof the ALARM (#4)position (FIGURE 10) Then, when the preselected time"arrives,

' the switch controlling member 18% swings into the ON I 2) position(FIGURE 11) for closing the radio switch j 115 and turning on the radio,but the camslope ldtlc continues to maintain outward pressure againstthe buzzer 'reedso that the buzzer will not thereafter sound as long 1Thus, when the preselected time arrives, the switch controlling memberlSd swings into the ON (#2) position (FIGURE 11) for closing the switchbut no sound or a minimum amount of sound is emitted by the radioApproximately 10 minutes after the switch controlling member has movedinto this"ON (#2) position (FIGURE 11'), the continued upward movementof the time responsive lever 110 trips out the latching shoulder 11% andpermits the buzzer control lever 16% to swing'the valley depression 16%into register withthe lip end of the buzzer reed,

whereupon the buzzer starts to sound. If it is desired to have thebuzzer begin sounding more nearly to the preselected time, the settinggiven to the time set table gear must be advanced slightly to compensatefor the above 10 minute delay. 1 v

This completes the cycle of most or all of the control functionswhichcan be performed manually by the rotation of the indexing 'knob 43, andwhich can be performed automatically by the timed movement of the timeresponse lever pursuant to the establishment of a preselected timesetting on the time settable gear 95.

Attention is directed to the fact-that in my improved construction thefour position indexing knob 43 always indicates the true position of theelectrical switch i.e. it always indicates whether the radio (or otherconneotedappliance) is energized or not. In different competitivedevices thathave come to. my attention, I have 7 found that theirindexing'knobs or indexing" shafts do not advance or change positionwhen the electrical switch closes .to turn on' the radio automatically.Hence, with these competitive device s, if the radio volume is set low,or if the radio station which' has. been tuned in should 'go ofi theair, the radio couldIrernain energized all night or indefinitely. Inmyimproved construction, a mere glance-at the position designated by theindexing knob- 43 always tells whether or not the electric switch forenergizing the radio is or is not closed.-

Referring now to the so-c'alled SLEEP SWITCH con- 1 trol mechanism 45which is operated through the left hand setting knob 44, this knob 44and its rib 46' are rotatable through almost from a top position denotedby 0 on an associated indicating scale, down to a lower position denotedby 60 on the scale. The 0 position indicates that the SLEEP SWITCHfunction is not then operative or has not been set to function. The 60position indicates that the SLEEP SWITCH. function has been set toautomatically turn off the radio in approximately '60 minutes.

The rotatable'shaftdz on which the knob 44 is mounted extends rearwardlythrough the two frame plates 11 and 62, and has fixedly secured theretobetween these two 136' is'bearing against the bell crank arm 134.

' formed with an integral pinion 209 to provide for remote drivesituations where -the"SLEEP SWITCH function may bemade responsive to acontrol removed from the clockswitch 30. -A pin 211 projectingrearwardly' from the diegcasting 208 swings in an arcu-ate slot 212punched out of the rear base plate 62 to limit the range of rotativemovement of theknob' 44 substantially to the angular span between theand 60 marks on the front scale. A torsion spring 214 coiled around theshaft 42 in back of the die. casting 20 8 has one end be'aringagainstthe side of the stop pin- 211, and has its other end bearing against alug 215 punched forwardly from the lower end of the arcuate slot 212,this torsion spring normally tending to hold the knob and die casting atthe end of the front scale.

I The cam 1'36 rotates in the plane of the upwardly extending bell crankarm 134 of'the switch actuating lever 130; When the knob 44' is in its 0position this cam is spaced slightly fromthe' bell crank arm, but assoon as the cam is manually rotated into aset position, it swings itsraised dwell 136 over against the arm 134, oscillating the bell cranklever 1'30 downwardly into switch closing position. The fixed radius ofthe dwell 136' maintains the bell crank lever 130 depressed into aconstant switch closing position so long as the dwell The SLEEP SWITCHknob 44 can be turned to any inter.- mediateposition between the 0 andthe 60 positions when it is desired that the radio be turned off in ashorter interval of time, such as 10 minutes or minutes. When the SLEEPSWITCH cam 136 is rotated'into any desired position for establishing asleep switch interval for automatically turning off the radio the sectorgear 296 is also revolved into meshwitlr a time driven piniondrivingcone 223-, and the time driven pinion has the adjacent end of its hub22-4 for-med with a conical surface 225 for matching the frictiondriv'econe 223". Mounted I on the spindle 222 for free rotative andsliding movement thereon is a time driven gear 226 which derives itsconstant time driven rotation by its meshing relation with the timetrain gear 88. The inner end of this time driven gear 226 is formed withaconical' drive surface 227' which matches with a conical" drivensurface 228 on the adjacent surface of the pihion hub 224,so'thatthepinion 220 has a'friction slippage di'ive transmitted theretothrough its floating mounting'between the two'coni'cal'drive' surfaces223 and 228 The hub 224' base; very loose radially shiftable' fit aroundthe spindle between the two conical drivesurfac'es 2'23 and 227 sothatthe. pinion 220 can shift radially if thereshould be end to end abutmentbetween the teeth on the pinion 220 and the teeth" on the sector 206'when the sector swings into mesh with the pinion- 2202 A compressionspring 229' confined between the front side of the shi-ftable drivinggear226 and a washer 230bearing against the inner side of thefrontimounting-plate 61 serves to hold the driving gear 226 pressedrearwardly against the front side of the pinion hub 224; which, in

turn,-ser ves-to hold the rear side of the pinion hub 224 pressedrearwardl against the driving cone 223. It will be seen-from the foregoingthat when the sector gear 206 is swung into mesh with the time drivenpinion 220, should'there be any tendency to jam byreason of end-toendtooth abutment, the driving pinion 220 can readily accommodate meshingof the teeth by rotativefrictional slippage and also by inward radialshifting between the driving pinion and the conical drive surfaces 223and 228. The driving pinion 220* automatically center from fallingforwardly out of the slot 245.

with gear 88 of the clock train, the parts being so'proportion'ed as torevolve the sector gear 206' back through its 180 range of rotation inapproximately 60 minutes,

starting with the time marking 6O on the scale and going back to the 0marking. Y I

The forward end .of-the spindle 222 extends forwardly beyond the frontmounting plate 61 and has a drive pinion 231 mounted thereon. This drivepinion 231 ob- 'tains the benefit of the friction slippage timedrivendrive transmitted from the gear 22tl-to the spindle 222' by way I of thefriction, slippage conical drive surfaces 223 and 228. This drive pinion23-1 inoperative to transmit timed return rotation to a cam wheelconstituting part of the buzzer-delay repeat mechanism, previouslyreferred to as the 40-Winker mechanism 55.

Referring now to this'latter mechanism, and with particular reference toFIGURE 17, this mechanism is adapted to be actuated by theaforementioned vertically swinging lever 52 which projectsoutwardly-from one side of the device in position to be strokeddownwardly by the finger. This lever is mounted on a transverse pivot233 and extends out from-between the face plate 66 and front mountingplate 61. A stop wing 235 extends downwardly from the lever 52 forengaging the side of the device and thereby limiting the downward fingeractuated' stroke: imparted to the lever 52. The downwardly extendingactuating arm 236 of. this lever has a circular aperture 237 in itslower end which establishes pivotal swinging movement with a pivot lug238 projecting forwardly from an actuating link 240'. A tension spring.241 connected between the lower end of the link 240 and a notch in thefront mounting plate 61 normally tends to hold the link 240 in theretracted position shown. The link extends diagonally upwardly, and atits upper end is formed with arearwardly bent lip 244 which projectsrearwardly through a rectangular slot 245' punched out in the mountingplate 61', this slot 245 servingto guide the rearwardly bent hp 244' andto alford end stops for controlling its movement. plate 61 the hp 244isformed with along forwardly extending guide tongue 246 for preventingthe lip 244 The front edge of the rearward lip 244co'nstitutes anadvancing nose 244" formed on the outer front portion of the link 2'40,and this advancing nose is adapted to impart advancing movement againstsuccessive notched shoulders 247 formed in. the right hand peripheralportion of a cam wheel 251 which is rotatably mounted ona pivot stud 252carried by the mounting. plate 61'. Projecting rearwardly fromthecam'wheel 251 is a lug254which extends into an arcuate slot 255 inthe mounting plate 61 for limiting the range of oscillatory movement ofthe cam wheel 251. Formed in the upper portion of the'oarn wheel is afiat cam slope 256 which, in the normal position of the cam wheel 251shown in FIGURE 17, bears against or is spaced slightly from the inneror lower side of the lug 15-11 that projects forwardly from the edge ofthe vibratory reed through the slot 152. It will be seen from theforegoing that a single downward stroking of the finger lever 52 willoperate through the advancing nose 244 and first pawl tooth 247 toadvance the cam wheel 251 sufficiently far't'o bring the circular camdwell-257 against the lug 151for forcing the vibratory reed out wardlyinto its non-sounding position. Successive-downward strokes imparted tothe finger lever 52' are operative to cause'the advancing nose 244 toengage succeeding pawlteeth 247 for advancing the cam wheel 251 tomovemore of the arcuate length ofthe-concentric carndwell 257 under the lug151'. I p

As soon as the cam wheel 251' has-been; advanced In rear ofthe mountingV through one, two, or three steps, it begins slowly rotat-- ing back tothe normal position shown, which permits sounding of the buzzer., Thistimed return rotation is revolved into mesh with the teeth of. thecontinuously rotating time driven pinion 231, as soon'as the fingerlever is stroked downwardly either once, twice, or three times. Theidler gear 262 is capable of a spring resisted radial shifting movementif the teeth of the gear sector 261 should 'accidently have end to endabutment with the 7 end which is anchored against a lug punchedforwardly from the idler gear 262.. This spring normally holds the idlergear 262 shifted or thrust diagonally downwardly for effecting meshbetween the sector teeth 261 and the teeth or" the drive pinion 231, butthe spring permits momentary upwardshifting of the idler gear 262 if theteeth do not immediately mesh, suchupward shifting not disturbing themeshing relation between the sectors 261 i and 269, however.

As previously described in connection with-the friction slippage timedriven drive to the sector gear 2% of the SLEEP SWITCH mechanism shownin FIGURE 5, the time driven pinion 231 also receives the benefit of thefriction slippage time driven drive transmitted from the gear 226 to thespindle Z22. Hence, if there is any tendency of the teeth of the sectorgear 261 and the teeth of the pinion 231 to have end-to-end abutmentthis is further accommodated without injury by reason of the frictionslippage drive to the pinion 231. The timed relation of the drive fromthe spindle 222 to the cam wheel 251 is such as to cause this cam wheelto be driven back in a reverse direction to present the flat spot 256 tothe lug 151 after the lapse of a relatively short time interval from thedownward stroking of the finger actuated lever 52. Preferably, thisbuzzer time-delay interval is in the neighborhood of five to sevenminutes for one downward stroking of the lever 52. With the three pawlteeth 247 provided in.

the cam wheel 251, the lever 52 can be stroked downwardly three times inquick succession for establishing a longer cumulative delay periodranging up to or minutes before the buzzer will sound again; or with twodownward strokes the cumulative delay period would be approximately 10to 14 minutes; It will be understood that the number of pawl teeth 24'?may be increased beyond the three teeth shown.

In summarizing the SLEEP SWITCH mechanism 45, and the -Winker mechanism55, it will be seen that both are time driven back to normal positionsthroughthe single train of driving parts 88, 226, 223, 222, etc. ItWillalso be noted that the single friction slippage drivemechanism 223, 225,226 and'ZZI operates to transmit a time driven friction slippage driveto both the SLEEP SWITCH mechanism and to the 40-Winker mechanism.

While I have illustrated and described what I regard to be the preferredembodiment of my invention, nevertheless it will be understood that suchis merely exemplary and that numerous modifications and rearrangementsmay be made thereinwithout departing from the essence of the invention.a
